The issue actually only occurs after updating to 5.1.7. Restoring to 5.1.5 allows the site to load, but as of 5 minutes ago, installing 5.1.7 will trigger the application error.

I am also seeing 500 error after updating from 5.1.5 to 5.1.7

Thank for the speedy response, David. You were correct about that function being disabled and it was due to a configuration error that was easily corrected. Much obliged for your support and fast response.

Cheers!
